Deaminations via the Hydrazine 339 INTRODUCTION The replacement of an aromatic primary amino group by hydrogen is usually effected by reduction of the diazonium salt derived from the amine. ArNH 2 ->• ArN 2 + X- -* ArH + N 2 + HX It is evident that the success of the deamination process is a function of the completeness of diazotization as well as of the reduction. Fortu- nately, practically any primary aromatic amine is susceptible of diazoti- zation, usually in yields approaching the theoretical. The conditions for this reaction are comparatively standard and are fully described in monographs on the diazo compounds. 1 Diazonium compounds have been treated with a great variety of reducing agents, some of which have become incorporated into procedures
